ABSTRACT

A heat sink module and its siphon heat sink includes a transverse pipe member, a tilt pipe member, a first vertical pipe, second vertical pipes, fins, and a working fluid. The tilt pipe member having a low section and a high section is installed at the top of the transverse pipe member. Both ends of the first vertical pipe are coupled and communicated to the transverse pipe member and the low section respectively. Both ends of each second vertical pipe are coupled and communicated to the transverse pipe member and the high section respectively. The transverse pipe member, tilt pipe member, first vertical pipe and second vertical pipes jointly form a return pipeline. Each fin is coupled to the second vertical pipe. The working fluid is filled in the return pipeline. Therefore, the effects of separating gas and liquid channels and improving the heat dissipating efficiency can be achieved.

FIELD OF THE INVENTION

The technical field relates to a heat sink, more particularly to a heat sink module and its siphon heat sink.

BACKGROUND OF THE INVENTION

As science and technology advance, the computation speed of electronic components such as a central processing unit (CPU), a graphics processing unit (GPU), a north bridge chip or a random access memory (RAM) becomes increasingly faster, and the heat dissipation problem of the electronic component becomes more serious.

To enhance the heat dissipating efficiency, a siphon heat sink as shown in FIG. 1 is developed and available in the market, and the siphon heat sink comprises an upper transverse pipe C1, a lower transverse pipe C2, a plurality of vertical pipes C3, a plurality of fins C4 and a working fluid C6, wherein both ends of each vertical pipe C3 are coupled and communicated to the upper transverse pipe C1 and the lower transverse pipe C2 respectively, and the upper transverse pipe C1, the lower transverse pipe C2 and the plurality of vertical pipes C3 jointly form a return pipeline C5, and the fin C4 is coupled to the vertical pipe C3, and the working fluid C6 is filled in the return pipeline C5. The siphon heat sink is installed at a heat source, and the working fluid C6 achieves a cooling effect by the principle of a heated and vaporized gas flowing upward and a condensed and liquefied liquid flowing downward.

However, the aforementioned siphon heat sink still has the following drawbacks. Since the process for the gas-phase working fluid C6 to flow upward and the liquid-phase working fluid C6 to flow downward is achieved by the vertical pipe C3, therefore the content contained in the vertical pipe C3 may conflict with the gas-phase working fluid C6 flowing upward and the liquid-phase working fluid C6 flowing downward. Even worse, the gas-phase and liquid-phase working fluids C6 may conflict with each other clog the vertical pipe C3, and lower the heat dissipating efficiency of the siphon heat sink.

In view of the aforementioned drawbacks of the prior art, the discloser of this disclosure based on years of experience in the industry to conduct extensive researches and experiments and finally provided a feasible solution to overcome the drawbacks of the prior art effectively.

In FIGS. 2 to 4, the plurality of fins 5 is coupled to each second vertical pipe 4. In FIG. 2, a working fluid 6 is filled in a return pipeline p, and the working fluid 6 is a cooling medium selected form the group consisting of pure water, methanol, acetone, and R134A.

In FIG. 5, the casing 20 has a through opening 201 and includes a first channel 202 and a second channel 203 disposed therein, communicated with one another, and respectively and parallelly arranged at upper and lower rows, and the heat generating component 200 is contained in the first channel 202.

Further, the casing 20 has a partition plate 204 installed therein, and the first channel 202 and the second channel 203 are separated and disposed on upper and lower sides of the partition plate 204 respectively, and a first vent 205 and a second vent 206 communicated with the first channel 202 and the second channel 203 respectively are formed between the casing 20 and the partition plate 204.

In FIG. 5, the fan 30 is installed at the second channel 203, and the fan 30 has an air outlet 301.

In addition, the tilt pipe member 2 exposed from the through opening 201, a part of the first vertical pipes 3 and a part of the second vertical pipes 4 jointly define a cooling surface s2, and the cooling surface s2 is exposed to the outside to provide a cooling effect.

With reference to FIG. 2 for the assembly of a siphon heat sink 10 of this disclosure, the tilt pipe member 2 is installed at the top of the transverse pipe member 1, and the tilt pipe member 2 has a low section 21 and a high section 22 higher than the low section 21. Both ends of the first vertical pipe 3 are coupled and communicated to the transverse pipe member 1 and the low section 21 respectively. Both ends of each second vertical pipe 4 are coupled and communicated to the transverse pipe member 1 and the high section 22 respectively. The transverse pipe member 1, the tilt pipe member 2, the first vertical pipe 3 and the plurality of second vertical pipes 4 jointly form a return pipeline p. The fin 5 is coupled to the second vertical pipe 4. The working fluid 6 is filled in the return pipeline p.

In FIG. 2, after the working fluid 6 is condensed, the liquid-phase working fluid 6 flows towards a low position to the low section 21, so that the liquid-phase working fluid 6 naturally flows towards the first vertical pipe 3, and after the working fluid 6 is heated to form a gas-phase working fluid 6, and the liquid-phase working fluid 6 flows towards the first vertical pipe 3, so that the gas-phase working fluid 6 naturally flows towards the second vertical pipe 4 to achieve the effects of separating gas and liquid channels, preventing the gas-phase and liquid-phase working fluids 6 from conflicting with each other or clogging the pipeline, so as to improve the heat dissipating efficiency of the siphon heat sink 10.

In addition, the first vertical pipe 3 has a diameter a greater than the diameter b of each second vertical pipe 4, so that the liquid-phase working fluid 6 flows towards the first vertical pipe 3 with a larger diameter a more easily, and flows to the second vertical pipe 4 with a smaller diameter b less easily. Since the second vertical pipe 4 does not have the liquid-phase working fluid 6, the resistance in the pipe is low, and the gas-phase working fluid 6 naturally flows towards the second vertical pipe 4 to achieve the effect of improving the effect of separating the gas and liquid channels.

In FIG. 3, the transverse pipe 12 tilts gradually upward in a direction away from the first joint 11, so that the transverse pipe 12 can guide the gas-phase working fluid 6 to flow towards the second vertical pipe 4 naturally to improve the effect of separating the gas and liquid channels.

Therefore, the heat of the heat generating component 200 is guided to the air outlet 301 and blown out by the fan 30, and the heat is transferred to the transverse pipe member 1, and the working fluid 6 inside the transverse pipe member 1 is heated into a gas-phase working fluid 6, and the gas-phase working fluid 6 flows from each second vertical pipe 4 to the tilt pipe member 2. Since the tilt pipe member 2 is exposed from the through opening 201, and the tilt pipe member 2 is exposed to the outside, therefore the working fluid 6 of the tilt pipe member 2 can be condensed into a liquid phase, and the liquid-phase working fluid 6 returns to the transverse pipe member 1 from the first vertical pipe 3 to form a return pipeline p.

In FIG. 5, the transverse pipe member 1, a part of the first vertical pipes 3, and a part of the second vertical pipes 4 jointly define a heating surface s1, and the heating surface s1 is tilted with respect to the air outlet 301 to increase the surface area of the heating surface s1, so as to improve the heat dissipating efficiency of the heat sink module 100.
